Problems solved by technology
The conventional method of maintaining the state of the electromagnetic brake must supply power to the brake during the braking state and the brake release state, so that the brake consumes more power when the state is maintained, and the mixed iron car is a transportation equipment without a power source, and only a small capacity is installed. battery, which limits the power supply required by the brakes
In addition, most self-locking mechanisms are mainly used in hydraulic system devices, and the application of braking is less; the usual self-holding mechanism is composed of levers, pistons, guide plates and other structures, and the structure is relatively complicated

The invention relates to a torpedo car brake with a bistable state self-sustaining mechanism and a control method. The mechanism comprises a first part (51), a second part (52), a lead screw (22) anda speed reducer (6); the shaft part of the lead screw is sleeved with the first part and the second part; the fixed end of the lead screw is inserted into the first part; the free end of the lead screw penetrates through the second part and is connected with an output shaft of the speed reducer; each of the first part and the second part comprises a cross joint, an end cover (15), a nut (14), a nut guide pin (17) and a disc spring (12); the cross joint comprises a first supporting part (21) and a second supporting part (11); the first supporting part is of a sleeve structure and the end coversleeves an opening; the shaft part of the lead screw is sleeved with a nut and is nested with the nut guide pin (17) on the end cover; a disc spring ejector block (13) in the first part is provided with a disc spring ejector block pin shaft (20) and a limit switch; and a disc spring gasket and a disc spring in the second part are sleeved on the shaft part of the lead screw. The brake is simple instructure, and does not depend on electric power in braking and brake releasing states.
Description
technical field [0001] The invention relates to a brake system of a railway transport vehicle in a metallurgical enterprise, in particular to a brake for a mixed iron car with a self-holding mechanism in a bistable state and a control method. Background technique [0002] The original design of the mixed iron car (also known as torpedo tank car) does not have any braking system and device. It relies on the resistance generated by the locomotive to stop. car brake. [0003] After the molten iron transportation is unmanned, no one will be involved in the production site, and the mixed iron car needs to realize automatic braking and maintain the braking state and the brake release state. The conventional method of maintaining the state of the electromagnetic brake must supply power to the brake during the braking state and the brake release state, so that the brake consumes more power when the state is maintained, and the mixed iron car is a transportation equipment without a ...
